# Design sketch — multi-project deployments > Status: **draft / sketch.** Not binding. This precedes the SPEC edits it > describes. Decisions captured here were made interactively; open questions > are flagged inline. When this stabilizes it folds into `SPEC.md` (§1, §2, > §5, §6, §7, §8, §13, §14, §17, §20) and ships as a pre-1.0 minor with > upgrade steps. ## The reframe Today the framework hardcodes **deployment : corpus = 1 : 1**. One deployment is one Gitea content repo (`META_REPO`), one global slug namespace, one `VITE_APP_NAME` baked into the build, one flat catalog. SPEC §1 says it plainly: "this single repository is its content repository." This change makes it **deployment : project = 1 : N**, where *today's entire deployment becomes the N=1 case*. A **project** is what a corpus is now: a content repo, its own slug/`RFC-NNNN` namespace, its own catalog, philosophy, branding, member roster, and enabled-models universe. The **deployment** (the subdomain — e.g. Wiggleverse) becomes a thin shell hosting a directory of projects plus a shared account/notification layer. OHM becomes one project among several (specs, vision docs, …) under one deployment. The value of this framing: the migration stays mechanical. Everything deployment-scoped today splits cleanly into: - **stays deployment-scoped** — accounts, the beta/permission gate, the inbox, the bot service account, the Gitea org; - **becomes project-scoped** — the corpus, branding, roles, catalog, philosophy, enabled models. ## Decisions (locked) 1. **Project registry lives in git.** A registry (a `projects.yaml` / registry repo) declares which projects exist and their config; adding a project is a PR. Mirrored into a `projects` cache table. Keeps the git-is-truth invariant. 2. **Projects are membership-gated by default** (private). A non-member does not see a private project exists. `visibility` is still a per-project field with `public` and `unlisted` escape hatches (see §3) — gated is the default, not the only mode. 3. **RFC numbering is per-project.** Each project has its own `RFC-0001`, `RFC-0002`… computed as `max(existing IDs in this project) + 1`. ## 1. Git topology — one content repo per project One Gitea org for the deployment, **N content repos** (`ohm-content`, `specs-content`, `vision-content`, …). The bot already operates org-wide; it gains more repos and one registry repo. Slug uniqueness and `RFC-NNNN` sequences become naturally per-repo = per-project. Rejected alternatives: subdirectories in one repo (`projects//rfcs/…`) churns every path / branch-name / graduation code path and can't carry git-layer access control per project; prefixed slugs pollute the namespace. ### The registry repo A small repo (or a top-level file in a deployment repo) the bot reads and mirrors. Sketch shape: ```yaml # projects.yaml deployment: name: Wiggleverse tagline: ... projects: - id: ohm # url slug, stable, unique in deployment name: Open Human Model content_repo: ohm-content # repo under the deployment's Gitea org visibility: gated # gated | public | unlisted philosophy_repo_path: PHILOSOPHY.md enabled_models: [claude, gemini] # optional; falls back to deployment ENABLED_MODELS theme: { accent: "#5b5bd6" } # optional per-project token overrides ``` Project **definition/config** is in git; project **membership** is in the DB (it churns like `rfc_collaborators` and is app-state, not document state). The registry gets the same webhook + reconciler treatment as content repos. > Open: does the registry get its own repo, or is it a file in an existing > deployment/meta repo? Ties into the `ohm-rfc-app-flotilla` operator tooling, > which already owns deploy orchestration and could own registry edits. ## 2. Data model Introduce a **`projects`** cache table (mirrored from the registry, like `cached_rfcs` is mirrored from content). Then thread `project_id` through every RFC-scoped table. Hard constraint: once slugs are unique only *within* a project, any table keyed on `rfc_slug` alone is ambiguous, so `project_id` must ride along on all of them: - `cached_rfcs` — PK becomes `(project_id, slug)`; `rfc_id` unique per project - `cached_branches`, `cached_prs`, `pr_resolution_branches`, `proposed_use_cases` - `threads`, `changes`, `branch_visibility`, `branch_contribute_grants` - `stars`, `watches`, `pr_seen`, `branch_chat_seen` - `rfc_invitations`, `rfc_collaborators`, `contribution_requests`, `funder_consents` - `notifications`, `actions` ~15-table migration, all backfillable to a single default project (see §7). `api_graduation.py`'s `RFC-NNNN` allocator scopes its `max()` query by `project_id`. New tables: ``` projects( id TEXT PRIMARY KEY, -- 'ohm' name TEXT NOT NULL, content_repo TEXT NOT NULL, visibility TEXT CHECK (visibility IN ('gated','public','unlisted')), config_json TEXT, -- theme, tagline, enabled_models, … registry_sha TEXT, -- provenance of the mirrored row updated_at TEXT ) project_members( project_id TEXT NOT NULL REFERENCES projects(id), user_id INTEGER NOT NULL REFERENCES users(id), role TEXT CHECK (role IN ('project_admin','project_contributor','project_viewer')), granted_by INTEGER REFERENCES users(id), granted_at TEXT, PRIMARY KEY (project_id, user_id) ) ``` ## 3. Roles — three tiers A **middle tier** slots between today's deployment roles and per-RFC authority. | Tier | Who | Powers | |---|---|---| | **Deployment** (unchanged, narrowed) | `owner` / `admin` | Create/archive projects, manage all accounts, act in any project. The beta/`permission_state` gate stays here — it gates *having an account*, not project access. A plain authenticated user has an account but no implicit project powers. | | **Project** (NEW — `project_members`) | `project_admin` / `project_contributor` / `project_viewer` | `project_admin` = today's app-admin, scoped to one project (manage its membership, settings, graduate, act on any RFC in it). `project_contributor` = propose/branch/PR/chat. `project_viewer` = read + discuss only. | | **RFC** (unchanged) | frontmatter `owners`/`arbiters`; `rfc_collaborators` (`contributor`/`discussant`) | Same as today, now scoped within their project. | This is the existing owner → admin → contributor delegation pattern with a project axis added. `users.role` reverts to meaning *deployment*-level only. **Visibility interaction:** - **gated** (default) — invisible to non-members; must be a member to see it exists. Read and write both require membership. - **public** — any authenticated user can read; contributing requires a `project_contributor` grant. - **unlisted** — readable by direct link, not shown in the directory. > Philosophy tension to resolve in SPEC: today the app is open-by-default > (anonymous read, §11.1; admission gates only writing). Gated-by-default > reverses that for the common case. The `public`/`unlisted` modes preserve the > old behavior for projects that want it, and the deployment can choose its own > default posture — but §11 and §14 need rewriting to make "gated" the baseline > and anonymous read a per-project opt-in. **Discovery for gated projects:** since a stranger sees an empty directory, there must be a join path — invite-only (a `project_admin` adds you), or a request-to-join surface analogous to the existing §28 contribution-request flow. (Open — pick one.) ## 4. Branding & frontend (forced change) The one *forced* change. `VITE_APP_NAME` is baked at build time; you cannot bake N project names into one bundle. Branding moves to **runtime config served by the backend**: - `GET /api/deployment` → deployment name/tagline + the list of projects the caller can see (gated ones filtered by membership). - `GET /api/projects/:id` → that project's name, tagline, philosophy, theme tokens. - Frontend reads these instead of `import.meta.env.VITE_APP_NAME` (`App.jsx:208`, `Landing.jsx:16`, `BetaPending.jsx:17`). `VITE_APP_NAME` is deprecated → deployment name comes from the registry. This is a documented config change with upgrade steps per CLAUDE.md. Two chrome layers result: - **Deployment chrome** — the Wiggleverse header, the project directory / landing, a project switcher. - **Project chrome** — the current header / catalog / philosophy, now per project; theme tokens (`tokens.css`) overridable per project at runtime. ## 5. Routing & UX - RFC routes gain a project prefix: `/p//rfc/`, `/p//proposals/`, `/p//philosophy`, etc. - Root `/` becomes the **deployment landing = project directory** (the Wiggleverse home). For an anonymous or non-member visitor under gated default, that's only public/unlisted-by-link projects. - Breadcrumb gains a segment: `Wiggleverse / OHM / RFC-0042 · Human › main`. - The left-pane catalog (§7) becomes per-project; a project switcher lives in deployment chrome. ## 6. Cross-cutting — notifications, inbox, watches Accounts are deployment-wide, so there is **one inbox spanning projects** (§15). `notifications` and `watches` carry `project_id` so the inbox is filterable and a user can mute an entire project. Quiet hours / digest prefs stay per-account (deployment level). ## 7. Backward compatibility & migration The N=1 path keeps existing single-project deployments working: 1. Migration creates one **default project** from current config (`META_REPO` → `content_repo`, `VITE_APP_NAME` → `name`, visibility seeded to match the deployment's current open posture, likely `public`). 2. Every existing row's `project_id` is stamped to that default project. 3. An optional default-project redirect keeps old `/rfc/` URLs alive (308 → `/p//rfc/`). This is the SPEC §20 upgrade-steps block. ## 8. SPEC & versioning impact Touches §1, §2, §5, §6, §7, §8, §13, §14, §17, §20. Pre-1.0 minor with breaking changes spelled out (schema migration, `VITE_APP_NAME` deprecation, URL change, gated-default philosophy shift). Single-process SQLite stays fine — `project_id` is just a column; no DB-per-project, no Postgres forced. ## Operator-tooling integration (flotilla) Checked against the `ohm-rfc-app-flotilla` spec (the OHM deployment's operator control panel). It assembles a deployment from `{rfc-app@pin} + {non-secret overlay} + {secret pulls} + {corpus}`, **does not host the corpus** ("the corpus lives in a deployment-side repo"), and **depends on the framework only through versioned contracts** (`/api/health`, `VERSION`, CHANGELOG upgrade-steps, the `.rfc-app-version` pin). The framework knows nothing about flotilla. This confirms the registry decision and fixes how it integrates: - The registry is **deployment-side git content the framework reads** — same category as the corpus — *not* a flotilla-owned config blob. Putting project definitions in operator tooling would re-bake deployment specifics into the assembly layer and add a new framework⇄tool contract. - The framework reads the registry via a `REGISTRY_REPO` env var, the multi-project successor to `META_REPO`. Flotilla's overlay simply swaps one ref; its four versioned contracts are untouched. - Multi-project therefore ships to OHM as an **ordinary pinned-version upgrade**: bump the pin, run the §22.13 default-project migration, change `META_REPO`→`REGISTRY_REPO` in the overlay, deploy, verify via `/api/health`. No flotilla architectural change. ## Open questions - Gated discovery: invite-only vs. request-to-join surface? (drafted with both; M5 can ship invite-only first.) - Does the deployment landing itself need branding config, or is it derived entirely from the registry `deployment:` block? - Per-project `ENABLED_MODELS` resolution vs. deployment universe (§18, §6.6, §6.7 funder) — confirm fallback order. - Slicing plan for the build (mirrors DEV.md's original slice approach).
